Sergio Busquets attempts to strengthen his head

Tired suffering momentary head injuries that force him to fall to the ground clutching his face, even when little or no contact is made to other parts of his body, Sergio Busquets is apparently doing head strengthening exercises during Spain's training camp. With Andres Iniesta as his spotter, Busquets appears to be piledriving his own head into the ground to try and harden it.

Whether this works or just makes things worse remains to be seen, but you have to admire his determination to better himself like this.
